ABSTRACT
Global energy supply and demand are increasingly dominated by concerns about a range of factors, most notably climate change, shortage of oil supply and price increase, rising population levels, and energy consumption per capita. It is of vital importance to have an undisrupted supply of energy in a sustainable and secure way to meet the energy demand and maintain and improve the well-being of the community. Energy security is a critical element of regional security and stability. This chapter reviews a number of available zero or low emission technologies and their feasibility for introducing sustainability and energy security to road transport, namely biofuels, battery electric vehicles, hydrogen internal-combustion engine, and fuel cell vehicles. It emphasizes on the zero-emission hydrogen fuel cell option and its role to introduce energy security and sustainability to the road transport sector. The chapter discusses the hurdles confronting the development of hydrogen fuel cell technology for road transport and provides some practical strategies for future development.
